TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Aug. 18, 1908;

Application filed. March 14, 1904. Serial No. 197 ,963. v

To all whom it may concern:

Be it known that I, JACOB FELBEL, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and has for its main objects to provide an improved construction of type bar hanger, which is adapted to shield the type bar pivots from dust or grit, and to serve also as a guide for a type bar of improved construction, and also to provide means for starting the return of the type bar after printing.

In the accompanying drawings wherein like reference numerals indicate like parts in the various views, Figure 1 is a vertical frontto-rear sectional view of one form of typewriting machines embodying my invention, with such )arts omitted as are not material. Fig. 2 is a fragmentary front elevation of the segment with several hangers thereon, and their type bars shown partly in section. This view is taken on the plane represented by dotted line 1) .ofFig. 1, with some parts omitted. Fig. 3 is an enlarged plan view of a detached hanger and part of a type bar. Fig. 4 is a vertical, longitudinal section of the hanger showing the type bar returning mechanism. Fig. 5 is a perspective view of a hanger made of sheet metal.

Upon the base 1 of the machine are corner posts 2 which sustain a top plate 3. The top plate 3 supports a carriage (not shown) of i any desired construction, said carriage being provided with a platen 4, diagrammatically illustrated. Key levers 5, each having a finger-key 6 and returnin -spring 7, are piv-' oted at 8 in the rear of the base of the machine. Pivoted at 9 to each key-lever is a sub-lever 10 having at its lower end a slot 11 which cooperates with a fixed fulcrum-bar 12 extending from side to side of the machine beneath the key-levers. The upper end of each sub-lever 10 is pivotally connected at 13 to the rear end of an actuating link 14 which has its forward end pivoted at 15 to a type bar 16, supported at its type end on a segmental rest 17. The rest or pad 17 is in turn supported by several arms, of which 18 is one, which extend forwardly from the type bar segment 19. For the purposes of the in- 'slot 22.

vention it is immaterial whether the segment 19 be fixedly or movably connected with its brackets or supports, of which the left hand one 20 is shown. The hanger sup ortin part 21 of the segment has a series ofradia slots 22 in its front face, adapted to receive the hangers 23 and hold them against lateral displacement.

Each hanger has in its rear ortion a notch or cut-away 24, the cut-away 'ifurcating the hanger and providing forks by means of which said hanger fits over or embraces the hanger support 21 of the segment and at the.

same t1rne occupies its appropriate radial In this position the hanger 23 is secured 1n any suitable manner, as by a set screw 25 passing'through the rear wall or fork 26 and abutting against the rear of support 21, said screw, when turned in, drawing the front wall or fork of the bifurcation against the front face of the segment where by the hanger is secured to the segment in a fixed osition, but may be adjusted radially of said segment. The forward portion of the hanger is of an inverted U-sliape,,h'aving side walls 27 joining a top or roof 28. The type bar 16 is pivoted at 29 in the side walls; t side walls 27 and top 28 of the hanger thus forming a housing or hood for the type bar pivot. It will be evident that the pivots of all the type bars on the segment are thus protected from falling particles of paper, rubber and the like resulting from erasures, and the bearings are prevented from becoming clogged and working hard. In the top of the type bar hanger 23, and

somewhat to the rear of the pivot 29, is a slot 30 Which is adapted to receive-a lug or finger 31, on the type bar and projecting rearwardly and having a beveled end 32 to facilitate its downward entrance into, the slot 30. The type bar is formed with a cut-away or recess 33,whereby it is free to swing to printing position, (shown by the dotted lines in Fig. 1) when the finger key 6 is depressed, without striking the hanger. l

In the printing position the sides of recess 33 loosely embrace the top 28 of the hanger, and in normal position said sides are substantially parallel to the front face of segment 19. The thickness of finger 31 and the width of slot 30 are so related that in printing position the ty e bar is steadied laterally or 1s held from v1 ration longitudinally of the platen and correct alinement is obtained,

each slot 30 serving as an individual type,

guide for its associated finger 31.

The hanger 23 has a vertical perforation 34 (Fig. 4) centrally of the slot 33. The lower part of the perforation or chamber 34 is tapped to recelve a threaded cylindrical block or plug 35 which is screwed into it, the block 35 having a central hole which receives and guides the stem 36 of the spring plunger 37, which latter is movable in the perforation 34 and is guided thereby. The top of the lunger is maintained somewhat above the ottom of the slot 30 by a spring 38 surrounding the stem and bearing at one end against the block 35 and at its op osite end against the underside of the hea 39. To limit the upward movement of the plunger in the hanger, the stem 36 is provided with a head 39 contactive with. the bottom of the plug 35. As the type bar approaches the printing point, the finger 31, moving downwardly in the slot 30, contacts with the plunger 37 and resses it down against the action of the spring 38 until the type prints .and the finger key is released. Then the re-.

turn of the type bar to its normal position is started or assisted by the spring plunger acting upon the finger 31, said' plunger having the function of a repulser, its spring having been energized by the type bar as the latter moves towards the printing point, so that when the ty e bar is at the printing point the energized spring tends to force it away therefrom.

During the greater part of itsmovement from the rest 17 to the printing point and back again, the type bar oes not coact with the guide slot 30. It is not until the type bar nears the rinting oint, that it begins to cooperate with the gui e slot of its associated hanger, and the type bar swings away from the platen only a very short distance before it again separates from its guide. Useless friction during the major ortion of the travel of the type bar to and om the platen is thus avoided.

The hanger may be constructed in various ways within the sco e of my invention. For example, it may e formed from a solid block of metal by milling the slots 24 and 30 and the portion between the side walls 27 as shown. In this form the rear side and the upper portion of the hanger above the type bar pivot are closed. Or a hanger may formed by suitably punching out and folding appro riately a blank of sheet metal, and

provi ing it with a solid perforated and threaded support'40 for the screw 25 as seen at Fig. 5. In this latter construction. the type bar restoring means may be a flat spring 41, riveted at one end in the top of the hanger.

The type bar actuating means shown is of known construction; but I do not wishto be 1 guide, a type hanger and is recessed to receive a portion of limited thereto, as any other means for operating the ty e bar may be employed as well.

What I c aim as new and desire to secure by Letters Patent, is
